5e Lesson Plan - Freezing and Melting
Teacher:
Rachel Sauer
Subject:
Science
Grade:
1
Lesson Title:
Freezing and Melting
State Standard(s): grouped by subject and must be observable and measureable
Science and Engineering Practices
Construct an argument with evidence to support a claim. (2-PS1-4)
Disciplinary Core Ideas
Different kinds of matter exist and many of them can be either solid or liquid, depending on temperature.
Matter can be described and classified by its observable properties. (2-PS1-1)
Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are
reversible, and sometimes they are not. (2-PS1-4)
Crosscutting Concepts
Simple tests can be designed to gather evidence to support or refute student ideas about causes. (2-PS1-2)
Reading
(RI.2.1) Ask and answer such questions as who, what, where, when, why, and how to demonstrate
understanding of key details in a text. (2-PS1-4)
Writing
(W.2.7) Recall information from experiences or gather information from provided sources to answer a
question. (2-PS1-1),(2-PS1-2),(2-PS1-3)
Mathematics
(MP.5) Use appropriate tools strategically. (2-PS1-2)
Social Studies
3. Science and technology have changed daily life. (Ohios New Learning Standards)

Engage
Description: Introductory lessons should stimulate curiosity and activate prior student knowledge. The activity should
be a problem or an event that raises questions and motivates students to discover more about the concept.
Link to cognition: Students bring knowledge about how the world works but it is sometimes based on limited
experiences and sometimes on misconceptions.
What teacher does:
Create interest
Generate curiosity
Raise questions
Elicit responses that uncover what students know or think about the concept/subject
Purpose:
to activate prior knowledge
to capture students interest
to pose questions based on the objectives that the students will try and answer during the explore phase.
Activities: to accomplish the purpose above (reading,
demonstration, video, crazy statistics, interesting pictures)
Introduce topic and book
Read Wemberlys Ice Cream Star
Discussion after reading the book
Guiding Questions:
Introduction
What kinds of things have you seen melt?
What kinds of things have you seen freeze?
Based on the cover and title, what do you think
this story is going to be about?
During the Reading
Why would Wenberly worry about the ice
cream dripping?
Who do you think Petal is?
What was she waiting for?
Whats happening to her ice cream star?
Discussion after reading
What happened to Wemberlys ice-cream star?
Why did it melt?
Why did Wemberly want her ice-cream star to
melt?
Has anyone ever had popsicle soup?
Assessment: teacher observation, small group discussion, class discussion, drawing/chart/table/diagram,
notebook/journal, lab write-up, oral presentation, poster, quiz/test
Teacher informally assesses students based students answers to guided questions during class discussion
after reading the book.
Explore
Description: Students need the opportunity to actively explore the concept in a hands-on activity. This establishes a
commonly shared classroom experience and allows students to share ideas about the concept.
Link to cognition: Experiences occur before the explanations! Students are actively exploring with little explanation
from the teachers. Students acquire a common set of concrete experiences allowing them to help each other
understand the concept through social interaction.
What teacher does:
Encourage students to work together without direct instruction
Observe and listen to students as they interact
Explain
Description: Teachers use questioning strategies to lead students discussion of information discovered during the
Explore stage (may or may not be a hands-on activity). Teachers introduce new scientific terms (vocabulary) and
explanations at appropriate times during the discussion.
Link to cognition: When students engage in meaningful discussions with other students and the teacher, they can pool
their explanations based on observations, construct new understandings, and have a clear focus for additional
learning.
What teacher does:
Encourage students to explain concepts and definitions in their own words
Purpose:
To allow students to share what they have discovered
to create questions or techniques that will help students connect their discovery to the concept
to ask higher order level questions to solicit student explanations and help them to justify their explanations
Guiding Questions:
Introduction Questions
Based on the cover and title of this book, what
do you think the book will be about?
Sid is a kid who is very curious about science.
How many of you ever get curious about
science?
During Reading Questions
What does the word melted mean? (page 4)
Why wasnt the ice pop frozen when Sid
opened the freezer? (page 7)
Why do frozen things melt? (page 9)
Do you think that liquid can be frozen back into
ice? (page 12)
What is it called when something can change
back and forth from one state of matter to
another? (page 13)
Why did pouring the water onto the block of ice
help it to melt? (page 19)
Solid and Liquid Demonstrations
What is a liquid?
What are some other examples of liquids?
What are characteristics of all of these liquids?
Is a frozen popsicle a liquid?
If its not a liquid, what is it?
Elaborate
Description: Students are encouraged to apply, extend, and enhance the new concept and related terms during
interaction with the teacher and other students (in science, a hands-on activity).
Link to cognition: Providing additional active learning opportunities for students to incorporate into their mental
construct of the concept allows them to confirm and expand their understanding.
What teacher does:
o Expect students to use formal labels, definitions and explanations provided previously
o
Refer students to existing data and evidence and ask "What do you already know?" "Why do you think.....?"
Purpose:
to achieve a deeper understanding of the concept
to introduce new vocabulary that can connect to students new observations
to apply the new knowledge in their daily lives
Guiding Questions:
Before making pancakes:
How are pancakes made?
Do you think we could make pancakes right
now?
o Recipe on powerpoint
Teacher makes pancakes on the griddle
Students get to eat them after they have been made
Evaluate
Description: Students demonstrate their understanding of the concept.
Link to cognition: In student-centered instruction, it is important for students to be aware of their own progress as an
outcome of instruction. Students construct knowledge over time and may need additional experiences to refine their
understanding of the concept.
What teacher does:
Observe students as they apply new concepts and skills
Allow students to assess their own learning and group process skills
Ask open-ended questions, such as "Why do you think...? "What evidence do you have?" "What do you know
about x?" "How would you explain x?"
Purpose:
to allow students to demonstrate that they have achieved the lesson objective
to allow students to sumarize the big idea.
Assessment: teacher observation, small group discussion, class discussion, drawing/chart/table/diagram,
notebook/journal, lab write-up, oral presentation, poster, quiz/test
Students will complete fill in the blank questions from the powerpoint into their science notebook
